Furthermore, even though a user checks the level ofthe ink, the ink drops frequently.
  • the auxiliary ink container is installed at a place spaced away from the ink head, but the place is not fixed exactly, and so, the amount of ink supplied is changed according to the installation environment of the auxiliary ink container.
  • the conventional inkjet system has several problems in that the amount ofthe ink supplied to the ink head cannot be maintained uniformly and that the user must reprint due to stop of the supply of the ink because the system uses the osmotic pressure method.

  • the conventional inkjet system cannot print using lithographic materials because the auxiliary ink container is located under the inkjet head.
  • the present invention is directed to an inkjet printer system that substantially obviates one or more problems due to limitations and disadvantages of the related art.

Abstract

Cette invention a trait à une imprimante à jet d'encre servant à imprimer des lithographies et utilisant un distributeur d'encre placé à la suite de plusieurs têtes encreuses montées en parallèle. Cette imprimante à jet d'encre est constituée d'une tête d'impression (10) propulsant l'encre par jets, de dispositifs d'exposition aux ultraviolets (20) montés, sur un côté, sinon sur les deux, de la tête d'impression et ce, afin de faire sécher l'encre. Dans un autre mode de réalisation, cette imprimante se compose d'un réservoir à encre (110), contenant une quantité prédéterminée d'encre, d'un distributeur d'encre (150) recevant l'encre du réservoir et l'emmagasinant temporairement, ce distributeur (150) amenant l'encre à la tête d'impression (10). L'imprimante est également pourvue d'un réservoir à dépression (190) raccordé à un côté du distributeur d'encre, ce réservoir à dépression amenant l'encre sous une pression négative afin qu'elle ne parvienne pas trop rapidement à la tête encreuse. Cette imprimante est capable d'imprimer sur tous types de support, notamment sur des plaques d'acier ainsi que sur des articles à base de verre et de vinyle et ce, dans la mesure où, une fois projetée, l'encre est séchée directement par le dispositif d'exposition (20). Cette imprimante est également capable d'imprimer facilement des lithographies puisqu'elle améliore l'utilisation d'un récipient encreur auxiliaire (30).
